Of course, there's always a possibility that there are yet-to-be-discovered
harrier-type pterosaurs that use their feet to capture volant prey, like
falconiform harriers do today. If Padian's reconstruction of an
avian-style, patagium-free pterosaur leg are verified, against Unwin's
bat-like model, this raises that possibility.
